First off - cut yourself some slack. The title of your post, which labels her as 'abused' is misleading. If you've had her since 4 months of age, her fearfulness/anxiety is most likely genetic - NOT caused by something in her environment or anything you have done (or not done) I'd suggest looking into getting involved in Nosework. That's a wonderful way to help shy or anxious dogs gain some confidence, while demanding much less physical activity on the part of the human partner. Even if you don't pursue 'formal' classes, just Google 'nosework games for dogs' and you will get TONS of ideas to put her nose to use in creative & positive ways.
I will also encourage you to look up Debbie Jacobs. She has a book, website & facebook page all dedicated to working with fearful dogs. I guarantee that you will find some positive guidance there.
Also, have you talked to your vet - in depth - about her level of anxiety? She might be a good candidate for anti-anxiety medications along with a good, positive behavioral modification plan. Do you have a trainer that you are working with? If not, you would probably benefit from finding someone to help guide you along this path with your sweet, shy pup. Just make absolutely certain that they are highly qualified & only use positive reinforcement in working with timid dogs.
